Highlights |
• | The increase in the mass of scientific data, particularly in surgery, has inevitably led to the development of new so-called secondary research, namely systematic reviews. |
• | Data from systematic reviews can now be synthesized into tertiary research such as umbrella reviews. |
• | The number of umbrella reviews published each year is growing exponentially and will necessarily involve surgical research. |
• | This mini-review is an introduction to this new concept of clinical research and a presentation of its methodology, which is reminiscent of that of any systematic review. |
Summary |
Researchers and practitioners are faced with an exponential increase in the number of systematic reviews (SRs) (with or without meta-analysis), a so-called `secondary' research method that synthesizes data from primary research. This growing number, sometimes with discordant results on the same subject or with non-conclusions, has led to the introduction of the concept of reviews to synthesize SR in order to combine scientific knowledge useful to practitioners. These so-called ``umbrella reviews'' (UR) constitute a new tertiary research tool. Surgical research is no exception to this development but umbrella surgical reviews remain relatively rare. Any UR must be transparent and meet rigorous methodological criteria. The UR could thus provide answers to practical questions in the field of surgery, but only on condition that the bias of the included SRs is limited. Let us not forget that the base requirement of clinical surgical research remains the good methodological quality of clinical studies (primary research). Only thus can SRs or URs (secondary or tertiary research) be more useful and decisive.
